Spring @ExceptionHandler handling multiple kinds of exceptions

Question

I can\'t figure out how to handle more than one kind of exception by @ExceptionHandler.

I need to programmatically deal with these exceptions, for this I\'d need a shar

Answer 1

The @ExceptionHandler value can be set to an array of Exception types.

The implementation of using exception array as mentioned in Spring documentation will be like:

@ExceptionHandler({
    NotFoundException.class,
    MissingServletRequestParameterException.class
 })

Answer 2

Your question is rather confusing but your exception handler method will only handle one exception at a time. It will not catch multiple exceptions and then pass both of them into your handleFormException() method. If you need to handle these exception types differently then you should create an exception handler method for each one, specify an argument of that specific Exception type to your method, and then do the appropriate handling. For example:

@ExceptionHandler(DescriptionCstOrderException.class)
public String handleDescriptionCstOrderException(DescriptionCstOrderException exception, ActionRequest actionRequest) {...}


@ExceptionHandler(SpecializationCstOrderException.class)
public String handleSpecializationCstOrderException(SpecializationCstOrderException exception, ActionRequest actionRequest) {...}

// and so on...

Please refer to the Spring documentation for further information:

The @ExceptionHandler value can be set to an array of Exception types. If an exception is thrown matches one of the types in the list, then the method annotated with the matching @ExceptionHandler will be invoked. If the annotation value is not set then the exception types listed as method arguments are used. See the documentation for details.
